109. Review of the First $W$ Boson Mass Measurement with the ATLAS Detector

A precise measurement of the $W$ boson mass represents an important milestone to test the overall consistency of the Standard Model. Since the discovery of a Higgs Boson, the $W$ boson mass is predicted to 7 MeV precision, while the world average of all measurements is 15 MeV, making the improved measurement an important goal. Large samples of leptonic decays of $W$ and $Z$ bosons were...

377. The Weak Charge: From Atoms to the Z-Pole

Dr Mikhail Gorshteyn (University of Mainz)

6/1/18, 2:20 PM

TSEI

Parallel

I review the status of theoretical calculations that empower the precise determination of the weak mixing angle across the whole range of currently accessible energies. The key ingredients include the EW running of $\sin^2\theta_W$, and applications of the dispersion relations to radiative corrections that involve effects of the strong interaction. The upcoming low-energy experiments with...

280. Prospects for New Atomic Parity Violation Experiments

Gerald Gwinner (University of Manitoba)

6/1/18, 2:40 PM

TSEI

Parallel

Low-energy precision tests of electro-weak physics keep playing an essential role in the search for new physics beyond the Standard Model. Atomic parity violation (APV) experiments measure the strength of highly forbidden atomic transitions induced by the exchange of $Z$ bosons between electrons and quarks in heavy atoms. APV is sensitive to additional interactions such as leptoquarks, and...

367. Parity Violating Electron Scattering Experiments for an Ultra Precise Determination of the Weak Mixing Angle at Low Energies

Prof. Frank Maas (Helmholtz Institute Mainz)

6/1/18, 3:00 PM

TSEI

Parallel

Parity violating electron scattering off unpolarised electrons or unpolarised protons at low momentums transfer (well below Z-pole) is an ideal tool to test the Standard Model and search for BSM-physics up to a mass scale of about 50 TeV, complementary to the new physics searches at high energies at the LHC. The future MOLLER experiment at JLab and the future P2 experiment at the upcoming...

365. High Precision Extraction of $A_{FB}$ at the LHC

Prof. Arie Bodek (University of Rochester)

6/1/18, 3:20 PM

TSEI

Parallel

We report on the extraction of the electroweak mixing angle from precision measurements of the forward-backward asymmetry ($A_{FB}$) in dilepton events produced at the large hadron collider.
